DW: Got it.

Yes there is a challenge with the center of gravity.  Note the center of lift appears slightly aft of the front foil (because the back foil is also providing lift).  Their weight has to be centered between the two foils while riding ALL THE TIME.  Unlike with surfing you can't afford to shuffle around.  When we paddle in our weight if forward then we run back when we get up on a plane.  The tuttle box likely has to be further forward than would seem reasonable.

As I got off the phone with Stretch he said "Now I have to go a figure out where to put the damn fin box!"

I'm still thinking these are the wrong foil designs for SUP downwind. I need to get my ass in gear, but Peyote's motor comes first. Taking forever to build it right.
Foote 10'4X34", SIC 17.5 V1 hollow and an EPS one in Hood River. Foote 9'0" x 31", L41 8'8", 18' Speedboard, etc. etc.

Your ass would be better served on a different project. The existing foils are fine. The French make the best foils. Years of design and R&D. Buy one of those and slap it on a board and go. Learning to foil will be a project in itself.

Can someone who has a Naish or Starboard please measure the length of the nose logo and the length of the handle?

I'm looking for a unit of measure so we can get a good idea of how long the boards in the video are and where they put the tuttle.
Aloha, I welcome and appreciate all responses of positivity and good feeling.

IMO, Bruno André from AHD, blows the doors off of what I saw Connor and Zane trying to do in the waves with a foil for their brands, who are trying to play catch up...and, it still looked kinda funky...you decide...;-)

Saw this guy in the parking lot today.  His name is Dan (I believe), the designer and manufacturer.   He currently makes them for kite boarders.  Says it will cost half of what the ones currently on the market sell for, $500 vs $1,000.  This is due to the construction, aluminum vs carbon fiber.  Still needs some more R&D, this one did not have enough lift.  Interesting non the less.

Will it downwind?  :)  Sure whips a tight turn.

The length dimension of a 2014 Glide handle is 108 mm, aka 4.25 inches. Sharpen your pencil...

This very interesting thread has been going for a month, or more, so far. Lots of talk of pros and cons on the design.  Foils on surfboards, kites and windsurf, even drones. Evidently, the foiling movement is hot.

Now, beyond sponsored pros, tweaked equipment and the like, are there any mortals foiling downwind on an sup, that we can see on video? Better yet, against a proven dw board in bona fide dw conditions?

May all be well.

I'm not sure we even know that downwind SUP foiling is even possible yet, in any meaningful sense, do we? (I agree that watching eg. Kai Lenny with full boat support at one specific and rather special location doesn't really count).

I must say that I don't really see the attraction here, with what I've seen so far. The foil surfing for instance just looks like a poor version of normal surfing IMO - the turns are less dynamic, the footwork is largely gone, there's little variety etc. Apart from the novelty, I can't quite see the attraction. I'd still like to have a go, but I'm not sure this would ever replace "normal" SUP, or even be able to compete with it at any level. It kinda looks a bit monotone and restrictive to me, and I can't see a situation where it gives you a clear advantage. Does anyone know of one? By contrast, I can see plenty of situations where you'd be at a disadvantage.

Thanks!  Well by my very rough estimation the board in this video is right around 10' long and the foil is about 25" from the tail.

The hulls look similar to Hydroptere. 51 knots (58+ MPH) in 28 knots of wind:

The "attraction" to foiling is the same reason we are attracted to surfing, sailing, motorcycles, etc. - it's that feeling of flight.

I don't see it replacing non-foiled sups either, but anywhere there's real ocean close to shore with howling side shore winds and big swells, like Hawaii, it would be a blast.

I think decreasing drag/increasing lift...and, maximizing efficiency is worth pursuing...clearly advantageous for paddling a foil shown at the 36sec mark...

The foil that I ordered back in April has finally arrived and I'm ready to get it flying...in and out fog today making the wind go up and down...instead of our normnal steady thermal seabreeze...

The kite foiler that was out had to stay right on the edge of the fog bank and was pumping his kite feverishly...
I'm in process of converting one of my Mallet SUPs to accept the foil, as I think that there are some foiling opportunities...time will tell...;-)

Can't wait to get this windfoil up to speed...dunno if I'll be able to get it up over 30mph...which I can easily do on the board...
